Inno Setup Dependency Installer

Inno Setup Dependency Installer can download and install any dependency such as .NET, Visual C++ or SQL Server during your application's installation. In addition, it is easy to add your own dependencies as well.

Installation and Usage

1. Download and install Inno Setup 6.4+.
2. Download this repository or clone it.
3. Open the extracted ExampleSetup.iss file.
4. Comment out dependency function calls inside InitializeSetup function to disable installing them:

   Dependency_AddVC2013; // installed in example setup
   //Dependency_AddVC2013; // commented out and not installed in example setup

5. Modify other sections like [Setup] [Files] [Icons] as necessary.
6. Build the setup using Inno Setup compiler.

Integration

You can also just include CodeDependencies.iss file into your setup and call the desired Dependency_Add functions (some may need defining their exe file path before the include):

#include "CodeDependencies.iss"

[Setup]
; ...

[Code]
function InitializeSetup: Boolean;
begin
  // add the dependencies you need
  Dependency_AddDotNet90;
  // ...

  Result := True;
end;

Details

You have two ways to distribute the dependency installers. By default, most dependencies will be downloaded from the official website. Another way is to pack the dependency into a single executable setup like so:

• Include the dependency setup file by defining the source:

  Source: "dxwebsetup.exe"; Flags: dontcopy noencryption

• Call ExtractTemporaryFile() before the corresponding Dependency_Add function

  ExtractTemporaryFile('dxwebsetup.exe');

The dependencies are installed based on the system architecture (x86, x64, or ARM64). If you want to install 32-bit dependencies on a 64-bit system you can force 32-bit mode like so:

Dependency_ForceX86 := True; // force 32-bit install of next dependencies
Dependency_AddVC2013;
Dependency_ForceX86 := False; // disable forced 32-bit install again

A similar version exists for forcing 64-bit on arm.

If you only deploy 32-bit binaries and dependencies you can also instead just not define ArchitecturesInstallIn64BitMode in [Setup].

By default all added dependencies are installed for every user. You can tie them to one or more components so they are only downloaded and installed when the matching components are selected:

Dependency_Components := 'advanced'; // only install next dependencies if the 'advanced' component is selected
Dependency_AddDotNet100;
Dependency_Components := ''; // disable component gating again

Dependency_Components accepts the same expression syntax as Inno's Components parameter (e.g. 'feature1 or feature2').
